this is how Redmi note 7 records audio in loud place: https://youtu.be/sPrdprlOJMo total disaster, noise, distortion. Samsung, Iphone, PPTV King 7 record audio ideally in the same conditions: https://youtu.be/v9kMncLgaew?t=211 (sample on King 7). Can developers please test and improve microphone parameters in /system/vendor/etc/mixer_paths_wcd9326.xml |
ctl name="ADC1 Volume" value="12" /
ctl name="ADC3 Volume" value="12" /
some guy on forum suggested to write "6" there for better sound, i could not test it because of no root rights. Ideal would be: in case of low volume in recording place - AGC rises mic sensitivity (currently recorded audio is silent, I must add volume on speakers to the maximum to hear something). In case of loud/bass music mic sensitivity goes to the minimum, to avoid distortion. Just the way autobrightness works for the screen, Automatic Gain Control
